Tip: mouthwash against Staingate on Retina display?

My old MacBook Pro Retina from 2014 has the Staingate spots typical of the model series on the display. Now I have heard that the places can allegedly remove with mouthwash. What do you think of it?

The stains arise because the anti -reflection coating of the display comes into contact with dirt or fat and slowly dissolves.

Even if you don’t touch the panel, remnants of hand creams, soaps or dirt can remain on the keyboard. They are then pressed against the panel as soon as you open the lid.

In fact, there are some tips on the net to remove the stains with mouthwash. Strictly speaking, however, the rinsing removes the anti -reflection layer because alcohol and the essential oils attack it.

As soon as the entire reflection layer has been removed, the display has a stain -free effect again. However, it reflects very strongly afterwards. To remove the stain, you should first switch off the MacBook and place it opened on the back of the display. Then clean the screen with a slightly damp microfiber cloth. Then wet a second cloth with an alcoholic mouthwash like Listerine. With this wiping in a circular movements and with little pressure over the stained screen. You should wear one -gloves during the procedure.

With long and thorough “cleaning” you remove the entire reflection layer in this way. Then remove any streaks with a clean cloth moistened with water.

We tried the method on a defective MacBook with similar spots: the layer loosened a little on the edges, but was extremely stubborn, especially in the middle of the display. However, we could not completely remove the coating after an hourly cleaning attempts. However, some users report that the method can take several hours. There is also a risk that the screen will be damaged. For example because you press too tightly and the sensitive panel breaks or you apply too much liquid, which then pulls into the device into the device.

Precisely because Apple no longer keeps spare parts for the old Retina MacBooks, we rather advise against the procedure. So you should only carry out the stain removal if you can accept that the MacBook breaks.
